Part of spiritual evolution is born when one's identity is no longer tied to material things.

If there is free energy, transport and replicators all distributed, we will become the same.

Nobody will be enslaved, people will just do what they want to do, have free time, time to think and be creative.

There's no reason to hoard anything.

Advanced civilizations don't wonder where their next meal WILL come from, how to pay their rent, how to get from A to B.

That's the future ...
